Difficulty: MediumEcological Factors and Their Measurement

Match each ecological measuring instrument in the left column with the corresponding abiotic factor it measures in the right column.

  • HygrometerRelative humidity of atmospheric air
  • AnemometerWind speed in terrestrial habitats
  • Secchi discWater turbidity and light penetration in aquatic ecosystems
  • BarometerAtmospheric pressure across varying altitudes

Answer

Hygrometer pairs with Relative humidity; Anemometer pairs with Wind speed; Secchi disc pairs with Water turbidity and light penetration; Barometer pairs with Atmospheric pressure.
Each measuring instrument is correctly matched to its specific environmental variable: Hygrometer to relative humidity, Anemometer to wind speed, Secchi disc to aquatic turbidity and transparency, and Barometer to atmospheric pressure.

Step-by-Step Solution

1
Determine the parameter measured by a hygrometer.
A hygrometer quantifies moisture levels in the atmosphere.
Atmospheric moisture level is referred to as relative humidity.
2
Determine the parameter measured by an anemometer.
An anemometer quantifies the rate of airflow in terrestrial environments.
Airflow velocity is defined as wind speed.
3
Determine the parameter measured by a Secchi disc.
A Secchi disc measures clarity in aquatic environments based on visual disappearance depth.
Clarity in aquatic environments corresponds to water transparency or turbidity.
4
Determine the parameter measured by a barometer.
A barometer measures force exerted per unit area by the weight of air above.
This force per unit area is atmospheric pressure.
